Abstract Background and Aims: Cover crops have the potential to aid in adapting agricultural systems climate change impacts through their ecosystem services, such as preventing soil erosion, remediating structure, storing carbon belowground. Though roots are integral these processes, there is a lack of cover crop root trait data. This study aims characterize rooting behavior several commercially available assess how differences system architecture potentially impact selection for services. Methods Twenty-two cultivars across grass, legume, brassica families were grown O’Fallon, Missouri, USA. Canopy was monitored throughout growing season. Shoot biomass samples collected analyzed. Results Cereal rye winter triticale most hardy provided highest percent canopy cover. also generated amount shoot among treatments but diverged architectures. Winter forms coarser exhibited deeper rooting, which may be better suited sequestration. Rapeseed Siberian kale favorable C:N ratios nutrient recycling, rapeseed invest more into lateral formation higher “catch” excess nutrients. Conclusion Selection services should account suitability Differences traits within same family highlight breed further enhance service efficacy.

Abstract Background and aims Most studies of the relationships between composition soil organic matter plant cover have been carried out at genera level. However, they largely overlooked potential effects that varieties, belonging to same genus, can on matter. Methods We investigated whether varieties different Salix species ( S. dasyclados viminalis) impacted using mid-infrared spectroscopy pyrolysis GC/MS. Top-soils were taken from an 18 year-old long-term field trial where six grown as short-rotation coppice under two fertilisation regimes. Results Significant differences in molecular diversity observed fertilised plots. The mostly visible level, i.e. had higher lignin content than viminalis , potentially due amount their litter inputs. Smaller among also observed. No significant unfertilised relatively high degree spatial variability several properties found these plots may masked variety and/or effects. Conclusion This study provides evidence identity or affect corresponding traits should be considered breeding programmes enhance C accumulation persistence.

Yet, they largely overlooked potential effects that varieties belonging to same genus can on matter. Methods We investigated whether different Salix species ( S. dasyclados viminalis) impacted using mid-infrared spectroscopy pyrolysis GC/MS. Top-soils (0-20 cm) were taken from an 18 year-old long-term field trial where six grown as short-rotation coppice under two fertilisation regimes. Results Significant differences in molecular diversity observed fertilised plots. The mostly visible level, i.e. viminalis , though smaller among also observed. No significant unfertilised plots, possibly due relatively high degree spatial variability several properties (pH, total N C contents). Conclusion This study provides evidence taxonomic distance, affect Such effect should be considered breeding programmes for managing C, it is one driver persistence soils.

Abstract Near-term commitments to net-zero greenhouse gas emissions (GHG) require the agriculture sector reduce and sequester CO2. Harvesting of crop residues can contribute these goals; however, uncertainties about effects on grain yield, non-CO2 GHGs, soil health have led questions potential benefits residue harvest. Here, we show that harvest are underestimated growing because they do not account for increasing rates production attendant agronomic environmental partial In North America, maize is by > 100 kg ha-1y-1. Partial increase yield 6% N2O 30%. These greatest when paired with conservation tillage grow production. A systems approach integrates practices mitigate GHG promote farmer adoption.
